Verdict

The call

The clearest difference is in-app purchases: Model Release Form at none against LExp's 2. Model Release Form also leads on review sentiment (100% vs 81%) and price ($1.99 vs $3.99). LExp's advantage is rating (4.7 vs 4.3). On ratings volume, update cadence, ads and monetization model there is nothing between them.
